Ajax Live Data Search using jQuery PHP MySQL

The following PHP MySQL live data search javascript/jQuery and ajax code will search data from database and display without refresh/reloading whole web page:

  • Step 1 – Create PHP Project Directory
  • Step 2 – Create phpmyadmin MySQL Database and Connecting File
  • Step 3 – Create Ajax Live Search HTML Form
  • Step 4 – Create ajax-search-db.php

Step 1 – Create PHP Project Directory

In step 1, Navigate to your local web server directory. And inside this directory, create one directory. And you can name this folder anything.

Here, I will “demo” the name of this folder. Then open this folder in any text editor (i will use sublime text editor).

Step 2 – Create phpmyadmin MySQL Database and Connecting File

In step 2, you need to create database and table. So run the following sql query to create database and table:

Then create a php file that named mydbCon. Which is used to connect phpmyadmin mysql database to project (demo).

So, now create mydbCon file and add the below given code into your file:

CREATE DATABASE my_db;


CREATE TABLE `customers` (
  `id` int(10) UNSIGNED NOT NULL,
  `fname` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `lname` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `email` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `created_date` date DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

Step 3 – Create Ajax Live Search HTML Form

In step 3, create a php file that named ajax-live-search.php. This file will display PHP MySQL live search box.

Here, i will use jQuery ajax to search from database without realoding the whole web page. Now, you need to add the following ajax live search html form code into ajax-live-search.php file:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>php mysql ajax live data search</title>
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">

    <script src="https://code.jquery.com/jquery-3.4.1.js"></script> 

</head>
<body>
<div class="container">
        <div class="row">
            <div class="col-md-12">
                <center><h2>PHP MySQL ajax live data search</h2></center>
            </div>
        </div>
        <br>
        <div class="row">
            <div class="col-md-6 col-md-offset-3">
                <!-- Form data start -->
                <form action="" method="POST" class="form-inline" role="form">
                    <div class="form-group">
                        <label class="" for="">Search a Query : </label>
                        <input type="text" name="search_term" id="search_term" autocomplete="on" placeholder="search user name here...." class="form-control search_term">
                    </div>
                </form>
                <div id="data-container"></div>
                <!-- Form data end -->
                <div class="selected_data_containter" id="selected_data_containter">
                    
                </div>
            </div>
        </div>
    </div>
</body>

<script type="text/javascript">
$('#search_term').keyup(function() {
    var search_term = $(this).val();
    var key = {
        search_term : search_term
    }
    var resp_data_format="";
    $.ajax({
        url:"ajax-search-db.php",
        data : key,
        method : "post",
        dataType : "json",
        success : function(response) {
            for (var i = 0; i < response.length; i++) {
                resp_data_format=resp_data_format+"<li class='select_customer'>"+response[i]+"</li>";
            };
            $("#data-container").html(resp_data_format);
        }
    });
});

$(document).on( "click", ".select_customer", function(){
    var selected_customer = $(this).html();
    $('#search_term').val(selected_customer);
    $('#data-container').html('');
});

</script>
</body>
</html>

Step 4 – Create ajax-search-db.php

In step 4, create new file that named ajax-search-db.php file. Because this is used to search form data into mysql database without realod the web page.

So, add the below code into your ajax-search-db.php file:

<?php
include 'mydbCon.php';

$search_term = mysqli_real_escape_string($dbCon,$_POST['search_term']);

$sql = "SELECT * FROM customers WHERE fname LIKE '$search_term%'";

$query = mysqli_query($dbCon, $sql);

$result = [];

while($data = mysqli_fetch_array($query))
{
	$result[] = $data['fname'];
}
echo json_encode($result);
?>
